Discovery Channel had seven shows in the Top 20. “The Golden Bachelor” led the “Bachelor” franchise shows—which are classified as participation variety shows rather than reality television shows in Nielsen’s data—in viewership this year. “The Golden Bachelor,” which was the most popular Bachelor premiere of the last several seasons, averaged 5.9 million viewers each week across its nine episodes, according to the Nielsen data. “The Bachelor” was the franchise’s next best-viewed show, with an average of 3.8 million viewers weekly, followed by “The Bachelorette” with 3.2 million average weekly viewers.
